“It’s refreshing to see the president state a policy and then follow through on it,” said Sen. Luther Strange (R-Alabama).

“I believe it was the right thing to do to go after that airfield.” Sen. Amy Klobuchar (D-Minnesota).

But while many in Washington applauded the move, some others who supported Trump very early in the campaign say they may be having a change of heart.

“There are some America firsters who are very upset about this,” said George Washington University Political Science Professor Dr. Michael Cohen in an interview Thursday, referring to voters who largely supported Trump’s campaign trail promises to always put America first.

There were dozens of examples on Twitter from some of the president’s original and loyal supporters, worried he’s turned away from that promise, including a tweet from @BasedMonitored:

Another former supporter, Paul Joseph Watson, declared“I’m officially off the Trump train.”

Other frustrations from Donald Trump’s earliest supporters include his appointment of so many former Wall Street Executives. Some have even said he’s filling the swamp he promised to drain.

Professor Cohen said it’s a reality many presidents face.

“Under the Obama administration you had the ultra-liberals versus the conventionalists. George W. Bush had to deal with the ultra-conservatives, the religious conservatives as well,” he said, adding that the real test will come during the mid-term elections when voters will see if that change in support will translate at the polls.
